i Application led September 30, 1910. Serial No. 584,652.

To all tczom it may concern:

Se it known that, l, Dirnnnr hns'r. a citizen of-the United States of America. residing.: at Detroit. in the county of rayne and State of Michigan, have invented certain new and useful Improvements in Manure- 'Spi-cadets, of which the followingis a l specification, reference being had therein to the accompaxrving drawings.

This invcntioil relates to manure spread-` ers of the type wherein the load is carried by an endless conveyer forming the bottom of the containingr box to the discharge end thereof, usually against a beater or other distributer.

The object. of the invention is to prevent any racing ot' the conveyor. when under load. and the uneven distribution' of the load resulting therefrom.A

The invention consists in the matters hereinafter set; forth, and more particularly pointed out in thc appended claims.

Referringr to the drawings, the ligure is a view in elevation of one forni of manure spreader thatT is equipped with a conveyer embodying features of the invention.

As herein indicated, a body l of a manure spreader has a conveyor track 2 traversed by an endless conveyor flight. 3 from end to end of the box which is substantially im 'perforale or solid nd is driven by any mnveuient form ot' transmission mechanism from the bearing wheels 4 on which the box is supported. The conveyer track has one or more vertical undulations indicated at 5 which he tlexible conveyor flight follows as it mores along the track. distrilnttin?r drum or heater (l driven by suitable mecha'.- nism from the bearingr wheels Il is diep( .l across the delivery end of the body to distribute the load evenly as il i moved against'J it by the conveyer flight. i under load, an tendency of the ilight to race in either diwctioa, as when the tractionA wheels drop into a hole or are otherwise momentarily 'retarded so as to allow slack or back-lash in the driving,r mechanism, is prevented h' portion of the conveyor which 1s pg over the nndulation of the bed. lf the flight tends to race forward the part of the load moving;l up the incline of the undulatiou tends to hold the flight back as a brake and conversely if the flight tends to run the other way the other slope of the nndulation retai ds its progress.

In practice, the bed may have as many undulations as is necessary to give the desired resistance and the track may be of any preferred forni or construction provided it has means for producing the required undulations in the conveyer. This construction prevents any racing and delivers the load regularly to the discharge end or to. the beater, there-y insuring' even distribution.

The conveyer flight may be of the return type. that is. an apron drawn along until the load is discharged, and then returned by appropriate mechanism to its initial position. the undulations of the track holding this form of con'leyer against racing as readily as one of the endless belt type.

Obviously changes in the details of construction may be mader withoutl departing from the spi,i it of the invention and I do not care to limit" myself to any particular form or arrangement of parts.

The slats or other members forming the flight are so disposed as to constitute a substantially solid or continuous surface through which material does not drop.

I claim as my invention 1. 1n a manure spreader, a horizontally dnlations, and traction bearing wheels supporting the box and having operative connections with the flight.

In a manure sp1 eader, bearing wheels, a box horizontally disposed on the wheels and pro\.led at one end with a discharge opening, a rotatable spreader drum jour- In testimony whereof I ax my signat'ure naled across the opening of the box and a in presence of two witnesses.
